A Parameter-Free Few-Shot Evaluation for Elephant Vocalisation Classification
Christiaan M. Geldenhuys, Thomas R. Niesler
We present a parameter-free episodic evaluation of nearest-centroid classification for elephant vocalisations on fixed pretrained acoustic embeddings, across the Elephant Voices (E…
Cough activity detection for automatic tuberculosis screening
Joshua Jansen van Vüren, Devendra Singh Parihar, Daphne Naidoo +4
The automatic identification of cough segments in audio through the determination of start and end points is pivotal to building scalable screening tools in health technologies for…
WhaleVAD-BPN: Improving Baleen Whale Call Detection with Boundary Proposal Networks and Post-processing Optimisation
Christiaan M. Geldenhuys, Günther Tonitz, Thomas R. Niesler
While recent sound event detection (SED) systems can identify baleen whale calls in marine audio, challenges related to false positive and minority-class detection persist. We prop…
Learning to rumble: Automated elephant call classification, detection and endpointing using deep architectures
Christiaan M. Geldenhuys, Thomas R. Niesler
We consider the problem of detecting, isolating and classifying elephant calls in continuously recorded audio. Such automatic call characterisation can assist conservation efforts…
